Heat olive oil in a large non-stick skillet over medium-high heat.
Add ground turkey, diced bell pepper, and onion to the skillet. Cook, breaking up the meat with a spatula, until the turkey is browned and vegetables are tender (approximately 7 minutes).
In a mixing bowl, whisk together the whole eggs, egg whites, garlic powder, smoked paprika, salt, and pepper until well combined.
Reduce skillet heat to medium and pour the egg mixture over the turkey and vegetables.
Stir gently and continuously to scramble the eggs until they are nearly set.
Fold in the black beans and chopped spinach, cooking for an additional 1-2 minutes until the spinach is wilted and beans are heated through.
Remove the skillet from heat and stir in the shredded cheddar cheese until melted.
Warm the tortillas in a dry pan or microwave for 15 seconds to increase pliability.
Apportion the protein filling equally into the center of each tortilla.
Fold the left and right sides of each tortilla toward the center, then roll tightly from the bottom to seal the burrito.
Optional: Place the assembled burritos seam-side down in the hot skillet for 60 seconds to crisp the exterior.
